I'm interested in a high-performance large formal fiber laser cutting machine. Specifically, I would like to know if it's possible to optimize the laser output to range from 1W to 60W. Additionally, I'm curious if the machine can be adjusted to operate a few feet above the cutting surface, as this flexibility would greatly enhance its versatility for different applications. Could you provide details on the customization options available for this machine? I'm particularly interested in any technical specifications, capabilities, and potential limitations related to the adjustments I'm inquiring about. Your insights would help me make a more informed decision regarding this investment.
